Root Causes: A PKI and Security Podcast

Latest Episodes:

Root Causes 668: AI in 1000 Days - Ownership of IP Sep 25, 2026

Show notes

In our ongoing series on how AI will change in the next three years, we discuss unresolved questions involving ownership of AI-created or -modified content. Plus, what happens when your AI steals intellectual property without your knowledge?

Root Causes 667: South Korea Has a Parallel PQC Program with Separate Algorithms Sep 23, 2026

Show notes

The NIST contest has not been the only government-led effort to discover qunatum-resistant algorithms. In this episode we describe South Korea's PQC contest, which is entirely independent of the NIST contest.

Root Causes 666: What Is a Scientifically Relevant Quantum Computer? Part 2 Sep 21, 2026

Show notes

In this second of two episodes, we finish our discussion of Scientifically Relevant Quantum Computers (SRQC) and their implications.

Root Causes 665: What is Quantum Security Posture Management (QSPM)? Sep 18, 2026

Show notes

We define a new term, Quantum Security Posture Management (QSPM) and explain what it is and why it's important for PQC plans.

Root Causes 664: What Is a Scientifically Relevant Quantum Computer? Part 1 Sep 17, 2026

Show notes

Much ado has been made about quantum computers breaking traditional cryptography. But that's not the reason so much effort is going into their creation. In this first of two episodes, we discuss the expected scientific applications for quantum computing architecture and the idea of a Scientifically Relevant Quantum Computer (SRQC).

Root Causes 663: The Trouble with Quantum Key Distribution Sep 11, 2026

Show notes

Quantum Key Distribution (QKD) is supposed to be this highly secure method of key exchange. But is it as secure as people say? We explore the potential weaknesses with QKD.

Root Causes 662: HAWK Eliminated from NIST Competition, FALCON Unaffected Sep 09, 2026

Show notes

We follow up on the recent Mythos attack against PQC candidate HAWK. We discuss the impact of this attack on both HAWK and FALCON.

Root Causes 661: What Will Happen with eIDAS and MTC? Sep 04, 2026

Show notes

TLS certificates from CA/Browser Forum CAs are not the only server certificates in the WebPKI. eIDAS QWACs are treated as server certificates by the major browsers. We see clear progress toward post quantum cryptography (PQC) for TLS by way of the Merkle Tree Certificate (MTC) architecture. But what is the path to PQC for eIDAS? We examine this question.

Root Causes 660: What Are Delegated Credentials? Sep 02, 2026

Show notes

As certificate lifespans become extremely short, new methods of delivery become functionally necessary. We explain RFC 9345 and how delegated credentials play a role in CDNs to deliver very short-lived certificates.

Root Causes 659: Should We Lengthen Certificate Lifespans? Aug 31, 2026

Show notes

With certificate lifespans shortening, we occasionally run into those who disagree with this trend and seek to lengthen maximum term once again. We examine regressive attitudes in PKI, why they occur, and the reasons that lessening security is generally a bad policy.
